Fabric.js Ellipse lockSkewingX Property

Last Updated : 25 Jan, 2021

In this article, we are going to see how to lock horizontally skewing of a canvas Ellipse using FabricJS. The canvas Ellipse means the Ellipse is movable and can be stretched according to requirement. Further, the Ellipse can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

To make it possible we are going to use a JavaScript library called FabricJS. After importing the library, we will create a canvas block in the body tag that will contain the Ellipse. After this, we will initialize the instances of Canvas and Ellipse provided by FabricJS and set the lockSkewingX of canvas Ellipse using lockSkewingX property and render the Ellipse on the Canvas as given in the below example.

Syntax:

fabric.Ellipse({
   rx: number,
   ry: number,
   fill: string,
   lockSkewingX: Boolean
});

Parameters: This function accept four parameters as mentioned above and described below:

rx: It specifies the horizontal radius.
ry: It specifies the vertical radius.
fill: It specifies the color to fill the ellipse.
lockSkewingX: It specifies whether to lock horizontally skewing of an Ellipse canvas or not.

Example: This example uses FabricJS to set the horizontally skewing of a canvas Ellipse as given below.
